It contains full binary decoding to select 1-of-8 data sources and feature strobe-controlled complementary 3-state outputs. The 3-state outputs can interface with and drive data lines of bus-organized systems. With all but one of the common outputs disabled (in the high-impedance state), the low impedance of the single enabled output drives the bus line to a high or low logic level.
Both outputs are controlled by the OE input. The outputs are disabled when OE is high. 3-state Version of HC151 High-current 3-state outputs interface directly with system bus or can drive up to 15 LSTTL loads 80 A Maximum low power consumption 9ns Propagation delay (typical) 6mA Output drive at 5V 1 A Maximum low input current Perform parallel-to-serial conversion Complementary outputs provide true and inverted data Green product and no Sb/Br Applications Industrial, Communications & Networking
